1/3″ 2.1mm 5MP F1.8 M12 Fisheye Lens
Unlock exceptional 2K panoramic clarity and outstanding low-light performance with our professional 1/3″ 5MP 2.1mm M12 fisheye lens. Precision-engineered for 5-megapixel (2K Ultra HD) image sensors, this high-performance lens captures a sweeping 165° diagonal field of view to guarantee total scene awareness. Featuring an ultra-bright F1.8 large aperture and an advanced 6G+IRCF (6 All-Glass Elements + Infrared Cut Filter) optical structure, it maximizes light transmission to deliver razor-sharp contrast and true-to-life colors while remaining completely immune to thermal focus drift. With its ultra-compact 20.3mm Total Track Length (T.T.L.), it stands as the premier optical choice for premium automotive vision, drone navigation, and high-end AI surveillance systems.
Key Product Highlights
- 5MP Ultra-HD Resolving Power: Precision-calibrated optics perfectly resolve fine textures on 5-megapixel sensor matrices, delivering flawless edge-to-edge definition for deep-learning analytics.
- 165° Sweeping Panoramic View: Captures a spacious wide perspective (136°H / 105°V) on 1/3″ sensors, comprehensively eliminating critical visual blind spots with a single camera module.
- Ultra-Bright F1.8 Night Vision Aperture: The exceptionally large F1.8 fixed iris vastly increases light throughput onto the sensor, ensuring bright, colorful, and low-noise imagery in dim or dark conditions.
- Resilient 6G All-Glass Structure: Built entirely with 6 precision layers of optical glass, maintaining an invariant focal plane under tough sunlight and extreme outdoor temperature changes.
- Optimized Distortion Profile: Controls horizontal geometric distortion down to <-49% (H), a highly refined optical engineering feat for a short-focus panoramic lens approaching 165 degrees.

Frequently Asked Questions
- Q: What are the main advantages of the F1.8 aperture on this 5MP lens?A: An F1.8 aperture is exceptionally large for an ultra-wide board lens. It allows significantly more light to strike the image sensor compared to standard F2.0 or F2.5 lenses, making it ideal for low-light night vision, reducing image noise, and capturing clear video in dark environments.
- Q: Can this 1/3″ lens fit smaller image sensors?A: Yes, absolutely. It can be mounted on 1/4″ sensor arrays. The field of view will crop naturally according to the sensor size, but the video will benefit from outstanding edge-to-edge sharpness.
- Q: What are the main benefits of the 6G all-glass structure on this fisheye lens?A: All-glass optics maximize light throughput and resist superficial scratches. More importantly, they prevent “thermal drift” (de-focusing) when camera modules run continuously or are deployed outdoors under direct sun glare, ensuring a stable focal plane.
- Q: How does the <-49% horizontal distortion affect my image?A: For a lens approaching a full 165° view, keeping horizontal distortion under 49% is an exceptional engineering design. It creates an immersive panoramic overview, and the barrel warping can easily be flattened out via backend camera dewarping software algorithms if a linear view is required.
- Q: How is the manual focus configured on this fixed focal M12 lens?A: Focus is set manually during your camera module’s assembly phase. The technician screws the lens into the M12 thread block while analyzing a live reference monitor. Once crisp focus at your target distance is established, it is permanently locked using a thread-locking compound or optical adhesive.
